Marking Permanency

Solder Process Recommendations:

In-line reﬂow:

Per MIL-STD-202G, Method 215J.

RoHS compliant, lead free. See solder proﬁle on page 4.

Refer to recommended reﬂow pre-heat and reﬂow temperatures on page 4. Package material

consist of Ryton R-4 high temperature cover with FR4 substrate. Component solder is Pb free high

temperature eutectic alloy with a melting point of 221°C.

In-line oven proﬁle:

We recommend using KIC proﬁler or similar device placing one of the thermocouples on the

device to insure that the internal package temperature does not exceed 221°C.

If for any reason the device needs to be removed from the board, use a temperature controlled

repair station with proﬁle monitoring capabilities. Following a monitored proﬁle will insure the

device is properly pre-heated prior to reﬂow. Refer to IPC 610E for inspection guidelines.

Removal of device:

Recommended Cleaning Process: (If required)

Device is non-hermetic, water resistance with four weep holes, one in each corner to allow

moisture to be removed during the drying cycle. We recommend in-line warm water wash

with air knife and drying capabilities. If cleaner does not have drying capability, then use hot air

circulated oven. Boards should be placed in the oven vertically for good water runoff.

Device must be dried properly prior to use!

Note: If saponiﬁer is used make sure the device is rinsed properly to insure all residues are removed. PH of saponiﬁer should

not exceed 10.

Drying Temperature:

Between 85 to 100°C.

Drying Time:

Time will vary depending on the board size.

Caution: Do not submerge the device!
